water imprint

What is the natural shape of plastic?
Most plastics are made of oil-derived liquid. Unlike wood, plastics do not have any original shape. We see them in all kinds of artificial shapes; plates, rods, pipes.
These shapes are made from molds.
There exist a soft boundary between resin and water. In the beginning, resin sinks to the bottom. When the reaction starts, bubbles start to build pillars and slowly forming a top surface above the water.
